51 Leonis Minoris (51 LMi)^[6] ye una estrella na constelación de Leo Minor. De magnitú aparente +7,62, nun ye observable a simple vista y alcuéntrase a 195 años lluz del Sistema Solar.

51 Leonis Minoris apaez catalogada nes bases de datos como una estrella mariella de tipu espectral G0, ensin que figure la so clas de lluminosidá.^[6] Tien una temperatura efectivo de 5839 ± 48 K y un radiu de 1,65 radios solares,^[7] xirando sobre sigo mesma con una velocidá de rotación proyeutada de 1 km/s. Con una masa cuasi igual a la del Sol, ye una estrella antigua con una edá envalorada de 8600 millones d'años.^[8] A diferencia del Sol, 51 Leonis Minoris ye considerada una estrella del discu gruesu^[9] como Arturu (α Bootis) o 171 Puppis.

Una carauterística notable de 51 Leonis Minoris ye la so baxa bayura relativa de fierro, equivalente al 40% de la solar. Les bayures relatives de manganesu y bariu tamién son inferiores a les del Sol, pero otros elementos, otra manera, son más abondosos que na nuesa estrella; asina la rellación europiu/hidróxenu ye significativamente mayor que nel Sol ([Eu/H] = +0,17).
